What can I use to release stuck window hinges and runners?

You can use WD-40® Multi-Use Product to release stuck window hinges and runners. Our original product is great for lubrication and to keep moving parts moving! However, if you are spraying near a painted surface, be mindful that WD-40® Multi-Use Product may cause stains. We also advise you to contact the manufacturer of the door or windows to ensure using products on them doesn’t effect your warranty!
